@RetroBitPixelI can confirm this also flickers for me on the map Discarded (this only did it once for me today, I played that map a few times and others were fine). 3090 user here, along with a 12900k, its just a broken game.
However, it does not do it all the time, but will randomly do it.. Its not your system, its just the game, my friend also has same issue randomly too. Its like it cant work out what geometry to cull so just flickers, as I think if you stand still it stops until move again?
If you are like me, you will probably look out for oddities, which is also a curse, i will actively look for them where as most people wont even care, curse of PC gamers hoping their hardware is not broken, its not your system, its fine, just a bug.
This was in some known issues back before xmas, so take it with a pinch of salt:
Discarded
- There are some rare instances of visual flickering while playing on Discarded (Xbox Series X|S, PS5, PC only)
